Read the whole thread. Rather concerned by the final one. "Locking temporarily" to get away from the discussion?

That feels sort of like the online discussion equivalent of sticking your fingers in your ears and going "la la la I'm not listening".

I don't expect someone in their position to be unable to ignore a conversation and "take a break" but I would expect them to be capable of doing so without resorting to "suppressing" the ongoing group discussion.

Or it's a "we're discussing internally, and would rather not deal with the shit-show that Github issues becomes once the issue becomes politicized and rampant misinformation and misguided activism take over."[1] There will be plenty of time for people to froth at the mouth and complain that they chose one way or the other once they've made a clear decision, which as of the locking the thread to collaborators, they have not (the current thinking has been outlined, but they said they are thinking about it).

I suspect your right, but honestly... His choice of language sounded much less like 'were thinking as a team', and much more like 'your all talking too loudly, you've given me a headache, so i'm going to shut you all up for a while'.

You mean the response that says, verbatim: "I'm thinking about the points that have been made, and I'm sure that we as a team will consider them going forward" ? Sure, he also says for now the behavior won't change, but that's the sane thing to do with the errors are rare, as changing something too quickly may introduce new bugs or unforeseen problems. Honestly, your interpretation of that comment is the exact reason why it's good to shut it down for a little while. The conversation gets so charged that even a "we need time to think about it" response is viewed negatively.
